- Lawrence bends a wire of length 18 cm

Mathematics
1 answer:

7 0

Answer:

1.02 cm²

Step-by-step explanation:

An equilateral triangle is a triangle with all three sides of equal length.

The perimeter of the triangle made by Lawrence is 18 cm. Which is calculated as follows:

perimeter of equilateral triangle = 3*side

Therefore, each side is 18/3 = 6 cm long

Area of equilateral triangle =  √3/4*side²

Area obtained by Lawrence = √3/4*5.8² = 14.57 cm²

Actual area of the triangle = √3/4*6² = 15.59 cm²

Absolute Error = | Measured Value - Actual Value |

Absolute Error = |14.57 - 15.59| = 1.02 cm²

It is known that 1.4< square root of 2 <1.5. Find all possible values of the expression 2-square root of 2. How do I find
horsena [70]

Answer:

0.5<2-√2<0.6

Step-by-step explanation:

The original inequality states that 1.4<√2<1.5

For the second inequality, you can think of 2-√2 as 2+(-√2).

Because of the "properties of inequalities", we know that when a positive inequality is being turned into a negative, the numbers need to swap and become negative. So, the original inequality becomes -1.5<-√2<-1.4. (Notice how the √2 becomes negative, too). This makes sense because -1.5 is less than -1.4.

Using our new inequality, we can solve the problem. Instead of 2+(-√2), we are going to switch "-√2" with both possibilities of -1.5 and -1.6. For -1.5, we would get 2+(-1.5), or 0.5. For -1.4, we would get 2+(-1.4), or 0.6.

Now, we insert the new numbers into the equation _<2-√2<_. The 0.5 would take the original equation's "1.4" place, and 0.6 would take 1.5's. In the end, you'd get 0.5<2-√2<0.6. All possible values of 2-√2 would be between 0.5 and 0.6.

Hope this helped!
